1 Application'filed March 22,

To all whom it may concern: I

Be'it known that I, ROGER FooARTY, a citizen of the United States, and a resident of Newark, in the. county of Essex and State of New Jersey, have invented a new and Improved Antiskid Device, of which the following is a full, clear, andexact description.

'This invention relates to an anti-skidding device of that type embodying chains which extend transversely across the tread of the The invention has for its-general objects to provide a simple, novel and effective means for attaching chains or equivalent elementsto a wheel so as to prevent skitlding, the'attaching means being in the form of an open spring ringthat lies concentrically toand inwardly from the felly, and which has overlapping ends with nutsl or equivalent removable devices on the ends so as'to prevent the ring from becoming automatically. detached from the antl skid chain's ,This construction is advanta eous,

as it can be easily and quickly applie the chains can be adjusted to any position, the resiliency ofthe retaining ring permits the ehains to yield under sudden, shocks so that reakage is prevented, the chains are held 37 but movably against the tireby the [resiliency of the retaining ring, the parting or breakageof any chain w1ll not interfere with theme. of the remaining chains, and the ring by being arranged on the outside of the wheel prevents any broken or. parted chain from becoming entangled with the hand brake or other part of the vehicle. With such objects in view, and others which will appear as the description proceeds', the invention comprises various novel features of construction and arrangement of parts which will beset forth with particularityl in the following description and claims appended hereto.

In the accompanying drawings, which illustrate one embodiment of the invention and wherein similarcharacters of reference indicate corresponding parts in all the views,

Fig. 3 is a transverse section on the line 33, Fig. 1'; and

Fig. his a transverse sectioii'showiug a modified form of the invention.

Referring to the drawing, A designates a vehicle wheel with the anti-skid device applied thereto, said device comprising a plu-' rality of chains,1 which extend transversely around the tire 2 and fellv 3. The chains are held in place by a.retaining ring 4' which ismade from a steel. rod of round, or other cross-section and bentinto an nular form of such diameter as to lie concentrically with. and inwardly from the felly of the wheel, the ends 5 of thering being free from 'each other and in overlapping relation, so that the ring can be opened forthreading on the anti-skid chainsl. On the ends of the ring are nuts or other stops 6 to prevent the ring,

from working loose from the chains.

,In Figs. 1 to 3 inclusive the ends of each chain' are brought into alinement so that the retaining ring can be threaded through the end links of the chain, but accordin to the' modification shown in Fig. 4, the en s of the chain are hooked intoclips 7 on a special form of attaching member which has an eye 8 through which the retaining ring passes.

In both arrangements the, chains are held firmly but movably on the tire by reason of the retaining ring being normally under. a tension. Any chain is free to yield when it encounters an obstruction or is subjected to shock, because of the resiliency of the retainin-g ring, and consequently the chains do not break, except when worn away. The

device is of extremely simple construction,- oi durable and substantial design and can be easily and quickly applied to or removed from a wheel. i

From the foregoing description taken in I 'connection with the accompanying drawings, the advantages of the construction and method of operation will be readily understood by those skilled in. the art to which the invention appertains, and while I have described the principie 'of operation, together the best embodiment thereof, I desire to have it understood that the device shown is .merely illustrative and that such changes be made when desired as fall within 105 may the scope of the appended claims.
